SPECIFICATION forming part of Letters Patent No. 71,030, dated April 2,1901 Application filed June 16, 1899. Serial No. 720,790. (No model.)

To all whom, it may concern:

Be it known that we, JOHN RAILTON, JOHN L. MCSPADDEN, and JOHN MCDONALD,citizens of the United States, residing at Detour,

in the county of Chippewa and State of Michigan, have invented a new anduseful Improvement in Bicycle-Frames, of which the following is aspecification.

The object of the improvement is to com- IO bine parts of both a frameand air-pump and so produce both frame and pump into one, and thusremove the necessity of having a separate pump. We attain this object inthe manner illustrated in the accompanying drawings.

Figure I shows frame and pump ready to attach to tire-stem. Fig. IIshows plunger, hollow plunger-rod, and rubbertube inserted intoplunger-rod. Fig. III shows combination in actual use in inflatingtires. Fig.1V

shows notch in rear part of saddle.

A represents a tube, which forms a part of the bicycle-frame and whichis entirely open at its top, but is closed at its bottom by means of thepartition G. Just above the partition there is formed an opening, andprojecting from the side of this tube around the opening is a nipple F,upon which one end of the rubber tubing E is placed when the tubing isbrought into play for the purpose of blowing up either one of the tiresof the wheels.

The seat-post J, instead of being made solid in the usual manner, ashere shown, is tubular and which fits in the top of the post A. The

seat L, which is secured to the seat-post in the usual manner, isprovided with an openingD through its rear edge, as shown in Fig. IV, sothat the upper end of the hollow piston-rods C can be freely operatedwithout having to displace the seat. The upper end I of this piston-rodO is curved rearwardly, so as to form a handle which rests upon the topof the seat-post when the piston II, secured to the lower end of therod, is depressed to its greatest extent. The seat-post being hollow,the piston-rod plays freely back and forth therethrough for the purposeof Operating the piston H for forcing air through the tubing E intoeither one of the tires of the bicycle. After the tires have beeninflated the rubber o tubing is removed from the nipple F, and then itis forced into the hollow piston-rod, as shown in Fig. II, without thenecessity of removing any Other part of the bicycle than the tubing.When either of the tires is being infiated, the tubing E, which has itsupper end to project slightly beyond the upper end of the piston-rod, iswithdrawn, and one end of the tubing is connected to the nipple F andthe other to the nipple upon the wheel that is to be inflated. Thepiston is then operated through the hollow piston-rod without having toremove any part of the wheel.

Having thus described our invention, we claim In a bicycle, the tube Aopen at its top,

and provided with a partition at its lower end, and with a nipple abovethe partition, and a hollow seat-post, combined with a seat having anopening through its rear end, ahollow piston-rod having its upper endcurved rearwardly so as to form a handle, and having a piston secured toits lower end, and the rubber tubing E which is adapted to be applied tothe nipple when one of the wheels is to be inflated, and tobe placedinside of the hollow pistonqod when not in use, substantially as shown.
